It eonsists of a hollowsorew, to be hereinafter more fnlly described, provided withlongitudinal slots 130 allow of the ready entranoe 0f the sap. It alsoconsists in having said sorew provided with a rim o1 projeoting edge toprevent a buoket o1 pail, whon hung thereon, from slipping oft,

und also in having tl1e head of said sorew provided with slits ornotehes for the entranoe of the point or end of a driver to force 01sorew the device into the -tree whendesired. It further consists inhaving the Sbid sorew made with a tapering hole, so that when the sap isin, it freezes and prewants the flow. As soon as it has begun to thaw 01melt, the pieoe 0f ice Will immediately slide out and allow the flow ofsap to continue. lt is evident that the hole must taper or dixninishtoward tl1e inner end of the screw.
